Salix alba, commonly known as the white willow, is a deciduous tree native to Europe and Asia. It typically grows near water bodies and can reach heights of 15 to 25 meters. The tree is characterized by its long, slender branches and narrow, lance-shaped leaves that are green on top and silvery-white underneath. The bark of Salix alba is grayish and deeply fissured, providing a distinctive appearance. This species is often used in landscaping and erosion control due to its extensive root system. Additionally, it has historical significance in traditional medicine, as it contains salicin, a compound related to aspirin.
